binary patterns
We use on/off for patterns, so I have rewritten the pattern handling,
removing the pattern_t type altogether, and changed it to use
binary strings of data instead. This uses less RAM for pattern definitions.
I have also changed blink_pattern to include morse code text
(generated by morse.pl), with kids' names.
